Trend Micro is trying to enforce a patent in order to collect money from competitors. One of the latest targets is Barracuda Networks. From the Barracuda Networks press release:
Campbell, Calif., Jan. 29, 2008 – Barracuda Networks Inc., the worldwide leader in email and Web security appliances, today announced it plans to defend itself, the open source community and the free and open source Clam AntiVirus software from a patent threat by Trend Micro. Barracuda Networks’ decision to take action comes after repeated requests from Trend Micro demanding Barracuda Networks remove ClamAV from its products or pay a patent license fee.
“Trend Micro’s actions illustrate that ClamAV and other open source projects remain vulnerable to commercial patent holders attempting to unjustly hinder the free and open source community,” said Dean Drako, president and CEO of Barracuda Networks. “Trend Micro appears to be seeking an interpretation of its ‘600 patent such that it would have exclusive control of gateway antivirus scanning. Scanning for viruses at the gateway is an obvious and common technique that is utilized by most businesses worldwide. So this interpretation would mean that anyone, including the owners of the more than one million active ClamAV installations, could potentially be sued by Trend Micro.”
The basic idea is that Trend Micro as a patent on detecting and filtering viruses at the Internet/e-mail gateway. ClamAV filters viruses at the gateway, therefore ClamAV allegedly violates the patent.
Barracuda Networks believes the patent is invalid due to prior art. That’s probably true, but it is irrelevant to the point I’d like to make. This patent, like so many others, is idiotic and should never have been granted.
The “Well, duh!” Test
This patent is typical of a group of patents that should all be filed under “absurd”. The easiest way to identify such patents is with the “well, duh!” test. Ask the fundamental question about the basis for the patent, such as “Does it make sense to scan emails for viruses as the emails arrive at the gateway?” The answer is clearly, “well, duh!” Whenever you get this answer, the patent should not be awarded.
Let’s expand on this just a bit to show when a patent application would fail the “well, duh!” test.
1. Q. Would it be cool to place speakers around the room to get a surround sound effect?
A. “Well, duh!” Patent denied.
2. Q. Would it be cool to be able to emulate surround sound with only two main speakers?
A. “Well, duh!” Patent denied.
3. Q. Is it cool to emulate surround sound with two speakers by starting with real-time analysis of the sound using a real-time fast-fourier transform on each of the 5 or 7 channels… etc?
A. “A fast what?” Patent remains under consideration.
The difference should be obvious. The third example takes REAL INTELLIGENCE and REAL WORK. Any idiot can figure out that it’s a good idea to create surround-sound with front speakers. It takes work and intelligence to come up with an idea on HOW to create a surround sound effect using only front speakers.
If anyone actually gets a patent on a common-sense good idea, it will be because they happened to get it to the patent office before anyone else could, and before anyone could establish prior art based on the same common-sense idea.
In short, the patent on HOW to create surround sound with two speakers is awarded based on a brilliant idea. It took intelligence, probably required some education and almost definitely required research. If a patent is awarded, it rewards this intelligence, research, etc. If a patent is awarded on the common-sense ideas, then what is rewarded is speed. The person who got the patent simply won a race to the patent office. Does this person or the company he represents actually deserve to receive a share of the profits made on products that implement these common-sense ideas? I argue that he/the company does not.
The Barracuda Case Argues for Patent Reform
In this author’s opinion, the Barracuda case is not about open source, even if it is an attack on open source. This case is yet another case that argues for patent reform. It is time for an overhaul of patent practices, especially software-related patents.
